Alabama linebackers Nico Johnson and C.J. Mosley have been two of the unquestioned leaders of the Crimson Tide defense heading into fall camp, thanks in large part to their years of experience with Nick Saban's complex defense.

On Monday, Johnson and Mosely shared their understanding of Saban's system with viewers of ESPN's SportsCenter during a segment breaking down their roles and duties as linebackers in Alabama's 3-4 defensive scheme.

Watch as Johnson and Mosely break down their defensive responsibilities to ESPN analyst (and former Georgia linebacker) David Pollack.
